Frozen Biome

Frozen Biome is a low temperature Biome of Ice and Snow.

Content
Frozen Biome has no Critters.

Sometimes Liquid Carbon Dioxide may naturally appear due to low temperature.

Note, that melting Ice and Snow tiles directly will grant twice more water, than through mining and melting. The only reason not to vent any excess heat towards frozen biome is that it will likely disrupt wild Sleet Wheat.

(Potential Bug: in actual game it seems the CO2 Lakes variant in Rime Asteroid is around -20 °C).

Gas Room
